The study by a team of international scientists ran 10,000 computer simulations of climate models in an attempt to explore the range of global warming predictions made by climate scientists.

The researchers found that while their results matched the predictions made by the Intergovernmental Panel on Climate Change at the lower end, they were higher than earlier predictions at the higher end.

They say that temperatures will rise by between 1.4 and 3 degrees by 2050.
